Subject: [PATCH] ALSA: hda: conexant: Fix headset auto detect fail in the polling mode

From: songxiebing <songxiebing@...inos.cn>

'Fixes: 7aeb25908648 ("Fix headset auto detect fail in cx8070 and SN6140")'

This patch only handles the unsol_event reporting during interrupts
and does not include the polling mode used to set jackroll_ms, so
it's changed to use snd_hda_jack_detect-enable_callback function.
